Trabalhar com múltiplos monitores é uma daquelas coisas que, juntamente com direção hidráulica e aquecimento a gás, uma vez que se prova, não dá pra viver sem. Depois de acostumado com o trabalho em dois monitores, me é difícil voltar a encarar apenas um monitor, é quase como se voltasse a gravar arquivos em disquete.
Para habilitar dois monitores no Sarge, é relativamente simples. O maior problema é a compatibilidade de suas placas de vídeo.
# XF86Config-4 para uso com dois monitores em duas placas ATI PCI.
# Algumas modificações serão necessárias para necesidades específicas,
# Mas essas não serão diferentes das alterações para uso em um monitor.
# Um how-to está sendo desenvolvido em http://www.debian-pr.org/pmwiki.php/MIB/MIBXinerama
# Em caso de dúvidas, STFW, RTFM e entre em contato com mailto:breno.moiana@gmail.com
